The gdsys gazerbeam board is based on a Freescale MPC8308 SOC.
It boots from NOR-Flash, kernel and rootfs are stored on
SD-Card.

On board peripherals include:
- 2x 10/100 Mbit/s Ethernet (optional)

The ppc4xx architecture was removed, and with it several old gdsys 44x

Except for one counter example, CONFIG_SYS_LBC_LBCR always has a value
of either 0x00040000 or 0x00000000.

CONFIG_SYS_LBC_MRTPR always has the value 0x20000000.

CONFIG_SYS_LBC_LSDMR_{1,2,4,5} are not set for any mpc83xx board.

CONFIG_SYS_LBC_LSRT is set by one board (to 0x32000000).

To simplify the configuration files, hardcode the setting of these
values for mpc83xx.

Migrate the BR/OR settings to Kconfig. These must be known at compile
time, so cannot be configured via DT.

Configuration of this crucial variable should still be somewhat
comfortable. Hence, make its fields configurable in Kconfig, and
assemble the final value from these.

We want to normalize all BR/OR config lines as much as possible.

The TQM834x board uses CONFIG_SYS_OR_TIMING_FLASH in a OR definition,
which we want to remove. But CONFIG_SYS_OR_TIMING_FLASH is also used
outside of the config file.

Replace these usages with the definition of the variable, so we can
remove the variable in the next patch.

The HRCW (hardware reset configuration word) is a constant that must be
hard-coded into the boot loader image. So, it must be available at

MPC83xx uses CONFIG_83XX_CLKIN instead of CONFIG_SYS_CLK_FREQ to set the
system clock. To migrate the architecture, we can replace
CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ.

To do this
* replace all occurrences of CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ
* set CONFIG_SYS_CLK_FREQ to the old value of CONFIG_83XX_CLKIN in all
  MPC83xx config files

The MPC8349EMDS config file contains config options to enable SDRAM

vme8349.h contains two separate boards: The vme8349 itself, and the

MPC8313ERDB has the option of either enabling NOR or NAND boot in its

When using DM_I2C the speed value supplied to setup_i2c() is not used,
so this code required CONFIG_SYS_MXC_I2C[12]_SPEED to be defined to
compile, but did not actually use them.

Change this so we no longer need to define an unused macro to compile in
DM_I2C mode.  Also make it more clear that they do not control the bus
speed.  Otherwise it is quite easy to mistakenly believe they are used
to set the bus speed.
